Menlo Systems has developed a series of detectors for lowest light level signals.
From avalanche to PIN photodiodes you can find the detector that is best for yourspecific application. All devices are field tested in our Optical Frequency Comb
Systems featuring Nobel Prize winning technology.

The Avalanche Photodetectors APD210,
APD310 and APD410, for detection inthe visible and near infrared range, respectively, offer a number of key features:
adjustable gain, high signal-to-noise
ratio and a temperature independent
gain characteristic through electronic
compensation of the bias voltage. Thedetectors are optimized for free spacedetection of optical pulses with a very
low signal level in the wavelength range
from 200 to 1000 nm and from 950 to1650 nm. They exhibit an extremely flat
frequency response over their 3 dB bandwidth.

PIN PHOTODETECTORSFPD310 SERIESThe high sensitivity ultrafast PIN photodetector FPD310 product family is optimized for high gain, high bandwidths,
extremely short rise times and highsignal-to-noise ratio. These photodetectors are easy-to-use Si- or InGaAs-PIN
photodiode packages with an integrated
high-gain, low-noise RF amplifier. Thegain can be switched between two fixed
settings, which allows an optimal performance for the user’s application.

Wavelength [nm]The high sensitivity ultrafast PIN photodetector FPD510 product family is
optimized for highest signal-to-noise-ratio
for detection of low level optical beatsignals and pulse shape at frequencies
up to 250 MHz. These photodetectors areeasy-to-use Si- or InGaAs-PIN photodiodepackages with an integrated high-gain,
low-noise transimpedance amplifier.
The high sensitivity ultrafast PIN photodetector FPD610 product family combines broad bandwidth and high gain
at frequencies up to 600 MHz. These
photodetectors are easy-to-use Si- or
InGaAs-PIN photodiode packages with an
integrated high-gain, low-noise transimpedance amplifier.
All models:
Available for both visible and near infrared range, both with either free space orfiber coupled optical input. The compact design of these detectors allows
for easy OEM integration. Included witheach amplified photodetector is a low
noise power supply, which features auniversal AC input.
